Mould Flow Analysis
Simulation detecting air traps, weld lines, and warpage before production.
Mould Flow Analysis is a simulation process used in plastic product manufacturing to evaluate how molten plastic flows inside a mould during the injection moulding process. This analysis helps engineers predict the behavior of the material before the actual manufacturing stage, reducing the risk of production defects.
A digital model of the product and mould is created using CAD software. Simulation tools then analyze factors such as material flow, temperature distribution, pressure levels, cooling time, and filling patterns within the mould cavity, helping engineers understand how the plastic will behave during injection.
Mould flow analysis is widely used to detect potential issues such as air traps, weld lines, sink marks, warpage, and incomplete filling. By identifying these problems early, engineers can optimize gate locations, wall thickness, and cooling channels to improve product quality and manufacturing efficiency — ensuring high-quality, cost-effective, and reliable injection moulded components before moving to mass production.
